​VISTA Problems loging to certain domains or workgroups

Give this a try:
1. Run secpol.msc.
2. Under Local Policies -> Security Options
Change the value of "Network Security: LAN Manager authentication level" from:
NTVLM2 responses only
to:
LM and NTLM - use NTLMv2 session security if negotiated
Let me know if that resolves the problem.
